What You Need to Know
Goldenseal is found in capsules, tablets, extracts, and teas for intake. The roots and rhizome, or underground stem is the part you find in goldenseal supplements.
The typical dosage of goldenseal depends on the form of the plant you consume. For example, for dried tea, you should consume 0.5 to 1 gram three times daily for best results. However, for a liquid goldenseal root extract that is 1:1 and 60% ethanol, you should consume 0.3 grams to 1 gram three times daily.
More studies are needed to confirm the benefits of goldenseal, or hydrastis canadensis. However, there are some studies that do show the aerial portions of this plant, or those parts exposed to air, to have antibacterial and anti-inflammatory properties. For example, goldenseal extract may help prevent infection and cell damage by methicillin-resistant Staphylococcus aureus (MRSA) bacteria.
Also, there is a 2017 study that looked at the effect of the flavonoids in goldenseal leaves that can enhance its antibacterial properties. Study results show three flavonoids called sideroxylin, 6-desmethyl sideroxylin, and 8-desmethyl sideroxylin,enhance the antimicrobial benefits of goldenseal.
In some people, you may have side effects after taking goldenseal like:
- Irritation of the mouth or throat
- Skin irritation
If you consume too much goldenseal, you may have overdose symptoms such as the following:
- Cardiac damage
- Low blood pressure
- Respiratory failure
- Shortness of breath
- Slow heart rate
If you have any of the above symptoms after taking goldenseal, be sure to seek medical advice and attention right away. Also, those who are pregnant, breastfeeding, have inflammatory digestive issues, have high levels of bilirubin in the blood, or children should not take goldenseal.
And although goldenseal is not known to have any drug interactions, berberine is known to interact with medicines like cyclosporine, robitussin, antidiabetes drugs, losartan, blood pressure drugs, blood clotting drugs, some anesthesia drugs, and sedatives. Therefore, be sure to check with your doctor before taking any new supplement.
